Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620180, here are decompositions:

29 + 8620151 = 8620180
47 + 8620133 = 8620180
59 + 8620121 = 8620180
71 + 8620109 = 8620180
131 + 8620049 = 8620180
137 + 8620043 = 8620180
311 + 8619869 = 8620180
383 + 8619797 = 8620180

Showing the first eight; more decompositions exist.
